Well this i a thin line isn't it...
In my opinion it should not be a problem for me to move the installation as long as I am the one maintaining it. Limiting a license to just run in one instance and on one server I fully understand. And this is how it should be.
I just want to be able to move it to, say another hosting company rather then hosting it myself.
Its not that much the cost, but I feel that if I pursues a solution like this, I should be able to run it from wherever I feel fit.
